Design Of Remote Monitoring System For Wind Turbine Cabin Environment

At present,wind power generation has become a promising and efficient form of renewable energy generation worldwide,so ensuring the safe and stable operation of wind turbines and improving the reliability of power supply is a top priority for the wind power industry.As the nacelle of a wind turbine is an important piece of equipment,the working condition of the electromechanical equipment in the nacelle is the basis for determining whether the wind turbine is working properly.This project designs a remote monitoring system for the working environment in the nacelle of wind turbines,mainly by collecting data on the working status of the relevant mechanical and electrical equipment in the nacelle,designing a control scheme for the monitoring equipment collecting the data and designing a transmission scheme for the data.The final network of individual wind turbines is designed to monitor the working status of each wind turbine in the background.The Raspberry Pi 4B is used as the main controller for this remote monitoring system,and the Raspberry Pi 4B is used to coordinate and control the individual monitoring devices.The main tasks accomplished in the thesis are as follows.Firstly,the causes of faults in the electromechanical equipment in the nacelle of the wind turbine are analysed,the monitoring needs of this remote monitoring system are determined and the type of characteristic data to be collected is determined according to the monitoring needs.Taking into account the actual working environment in the nacelle of the wind turbine and the scattered characteristic data collection points,each monitoring device is selected for mobile or fixed collection,and the installation points of each monitoring device are designed.Next,the monitoring requirements of the monitoring system are analysed to determine the control scheme for the data acquisition system and the entire control scheme is designed from the following aspects:selection of the main controller,analysis of the power supply requirements,selection of the driving method,design of the speed control and design of the positioning method to provide a good guarantee for the completion of the task of collecting the characteristic data.Next,the design of the feature data acquisition solution for the surveillance system is analysed and designed in detail.This includes the design of four feature data acquisition solutions:image,angle,audio and temperature and humidity.The reasons for feature data acquisition are clarified,the feature data acquisition equipment is selected and the feature data acquisition process is designed.Finally,a transmission protocol is defined to transmit the collected data to the server in a safe and stable manner,and a fibre optic ring network is designed to achieve the purpose of centralised monitoring of individual wind turbines.In this paper,the collection and transmission of feature data in the remote monitoring system of wind turbine cabin environment is designed in the context of monitoring the working status of electromechanical equipment in the wind turbine cabin,which will play a positive role in the development of remote monitoring technology of the working status of electromechanical equipment in the wind turbine cabin.
